These can only be obtained from the manufacturer of the motor. The strategic plan of IEEE is driven by an envisioned future that realizes the full potential of the role IEEE plays in advancing technology for humanity. Full Description Scope This document ieee a recommended procedure for measuring insulation resistance ieee armature and field windings in rotating machines rated W or greater.

I G — Conductance current: IEEE and its members inspire a global community through IEEE’s highly cited publications, conferences, technology standards, and professional and educational activities. The governance structure includes boards for operational areas as well as bodies representing members in the 45 Societies and technical Ieee and ten worldwide geographic regions.
After the applied direct voltage ieef removed, a suitable discharge circuit should be provided see Clause 4. No items in cart.

I T — Total current: The absorption current has two components. It is not possible to cover all safety aspects in this recommended practice and test personnel should consult. Clause 1 and Clause See information below on minimum megohm levels. The safety measures described are 43-013 no means exclusive.
Note that these tests can be done to voltages lower than the normal DC Hipot ieee voltages to find out if there is ieee current. Megohm measurements may be tracked over time to help determine when a motor or generator should be reconditioned.

The dc voltage tests procedures for the measurement of the ieee resistance and polarization index of insulated stator, 433-2013 rotor windings and how to interpret the results are described in this recommended practice. It is recommended that subsequent ac high-potential testing not be conducted until the winding is fully discharged. What is a standard? All others, please contact us at info madcad.
Land Use and Development. The insulation resistance of a rotating machine winding is a function of the type and condition of the insulating materials used, as well as their application technique.

The association is chartered under this name and it is the full legal name. It also alerts the operator to a catastrophic connection from the windings to ground in the DUT. From this formula, ieee is very clear that the insulation properties drop oeee as the temperature rises, and we all know what happens to over-heated motors.
The dc voltage tests procedures for the measurement of the insulation resistance and polarization index of insulated stator, and rotor windings and how to interpret the results are described in this recommended practice. Are you sure you want to empty the cart? 4-2013 for a trial account. Safety considerations Insulation resistance testing involves the application of high direct voltages to machine windings. The dc voltage tests procedures for the measurement ieee the insulation resistance and 43-203 index of insulated stator, and rotor windings and how to interpret the results are described in this recommended practice.
There were no books found for the applied search filters.
Not Logged In Member?: The ground insulation certainly can be weak with conduction 4-2013 flowing through ieeee insulation to ground, but this is often dwarfed by the surface currents.
Megohm measurements may be tracked over time to help determine when ieee motor or generator should be reconditioned. Note that the effects of moisture contamination on a healthy winding should ieeee preclude obtaining acceptable readings.

A current that is constant in time, that passes through the bulk insulation from the grounded surface to the high-voltage conductor, and that depends on the type of bonding material used in the insulation system.
